Every cloud really does have a silver lining... albeit thin, sometimes. So it is with the tragic suicide of Robin Williams. The actor's death is already prompting a national conversation about depression and other mental health disorders. And, in the case of this story by the American Society of Aging, the dialogue includes the incidence of depression in baby boomers, which is surprisingly high. Did you know that white men over age 60 have the highest rate of suicide in the United States? I sure didn't. That statistic should give us all pause. We need to remember to check in with each other often, and that means going beyond the cursory "How are you?" That's about all I've got to say. It's been a tough week.
